Did you do that trip of of Lee euro trips or on your own? Do you mind sharing the details? I'm looking at doing the same.
A dozen friends and associates booked our trip through Edelweiss, which is the premier motorcycle touring firm in the world. They do everything: provide the bikes (chosen from a rich menu ahead of time), a van, two guides, an itinerary, hotel bookings, etc.
The guides showed up at our designated hotel (in Erding, near Munich) in the van towing a long trailer with our bikes. They unloaded them and we had a long briefing on the trip, the route, the stops, the procedures, rules, etc. We started out the next morning, One guide drove the van with our luggage, and extra bike, tools and parts, and the other guide rode a bike to lead the pack. We generally rode about two hours between stops - a coffee stop in the mid morning, lunch, mid afternoon, and ultimately our hotel for the evening.
We went through all of the pretty mountain areas, often at full-sport speeds and leans. The weather was perfect, the roads/views beautiful, and the guides were superb. The guides took turns being the lead and in the van (the van took a straighter highway route to the next hotel). The guides were an Austrian man and a German woman. They were both expert riders but the guy was really really good. He said he wanted to enter the Isle of Man TT.
We had some diversity in bikes. I was on the XR. Other bikes included a Ducati Multistrada 1260, a 1200 RT, five GS/GSAs, and four Harleys. The latter were a real problem. While we had a spectrum of rider ability and risk aversion (I was behind the guide, then the Multi …) where we had to wait for others to catch up, the Harleys tended to be way, way behind. They didn't have the ground clearance or handling to keep up, and Harley riders tend to not be very good. The pack leaders would wait, often ten minutes, to regather the group.
One Harley rider had a terrible wreck, and it wasn't due to speed. (I was told) he was going about 50 km/h entering a town. The road veered left and he didn't - probably inattention and then target fixation, but no one really knows the cause. He went into the grass and then hit a tree. He flew into another tree where he got a nasty compound fracture of the right femur including destruction of the right knee, and a simple fracture of his left tibia. He was life-flighted to a German hospital where he spent several months. Despite most of us not knowing him, we donated many thousands of dollars to help him out. Sad.
Of course, I and most of the rest of us were many miles ahead when we got the call. We waited a while, but ultimately just went on to the next hotel on our plan. Another one of the Harley riders, his cousin, stayed with the injured rider, and the rest of us went on with the trip. We were very philosophical about the whole thing. We were there to tear up the Alps and have fun.
I can't tell you all of the amazingly beautiful areas we went through that included Germany, France, back to German, Switzerland (obeyed highway speed limits there), Lichtenstein, Austria, Germany, Austria and ending back in Erding.
The Austrian passes were probably my favorites where I did some of the more sociopathic riding ever, staying with my TT-aspirant guide, and leaving the rest way behind. I passed several flowered monuments on cliff sides to riders/drivers that didn't make it, but it was so viscerally intoxicating. I did slow down after a 120 degree turn on a cliffside where I looked down a couple thousand feet while leaned over 50 degrees; I just decided I needed to scale it back a wee bit.
But the trip was amazing. Great rides, hotels, friends, evening beers, professional everything, and Edelweiss was perfect. I couldn't recommend it more.
